  • biological organisms e.g., plants, algae, bacteria, animals
  • Paperboard and other paper products are often recognized as inherently sustainable or renewable materials as the trees and other plants that provide raw materials for the paper products can be and are routinely replanted in a sustainably renewable fashion.
  • the renewable and/or degradable material can be processed in injection molding applications, can be bonded or otherwise applied to a substrate (e.g., a blank or a pressed tray), has sealing, barrier, and/or venting properties, and/or has temperature resistance for heating (e.g., microwave and/or conventional oven) and/or for refr i gerati on/freez ing or other storage.

  • Other renewable and/or degradable materials can also be used without departing from the present disclosure.
  • the materials of the packaging material can have suitable properties for the particular type of construct made from the packaging material.
  • a construct that is a tray or other container for holding or serving a food product can comprise a barrier layer that is permeable or impermeable to certain gases, liquids, and/or other flowable materials (e.g., oils, oxygen, water, food products etc.).
  • a construct for heating a food product can comprise renewable materials with a temperature resistance of at least about 165 degrees Fahrenheit since it is often recommended to heat many food products to at least this temperature. Applications with lower temperature resistance requirements can include, for example, nonfood heating, heating beverages, reheating some food items, applications that only require storage and/or cooling, and/or other suitable applications.
  • Some applications can have higher temperature resistance requirements, such as for food products that require a higher external temperature in order to reach a minimum internal temperature, and/or for heating food products at least partially in a conventional oven, which can be set at higher temperatures for heating a food product via conduction and/or convection.
  • Other considerations for selecting a suitable material can include material strength for supporting the weight of a product and/or for stacking.
  • the packaging material can comprise a laminate structure 100.
  • the laminate structure 100 can include a substrate 102 and a composite layer 104 that is glued to the substrate 102 by an adhesive 106.
  • the substrate 102 can be a paper product (e.g., paperboard, cardboard, etc.) or any other suitable material (e.g., a material that is degradable, compostable, and/or repulpable).
  • the composite layer 104 may be a barrier paper, such as parchment paper, formed from a paper material that has been chemically treated to form a film that can be more easily laminated to a substrate.
  • the parchment paper is commercially available parchment paper suitable for use with (for example, heating) food products.
  • the parchment paper can be made by chemically treating paper pulp with chemicals (e.g., sulfuric acid, zinc chloride, or other suitable material), washing the chemicals off, and drying the treated paper.
  • the chemical treatment of the paper forms a sulfurized cross-linked material with high density, stability, heat resistance, and low surface energy.
  • the amount of grease resistance or porosity of the parchment paper will vary. High quality and high cost parchment paper will have high grease resistance or low porosity and low quality or low cost parchment paper will have low grease resistance or with high porosity.
  • the composite layer 104 could include any suitable paper material that has been treated, processed, etc.
  • composite layer 104 may be formed of a parchment paper that may have an at least partial porosity and/or permeability to the passage of materials therethrough (for example, caused by stray paper fibers, which can act as passageways, and/or other structural aspects of the composite layer 104).
  • Parchment paper and/or other paper products described herein are generally biodegradable, compostable, and repulpable.
  • the adhesive 106 can be a renewable and/or degradable adhesive.
  • the adhesive 1 06 is generally degradable, compostable, and/or repulpable with the composite layer 104 and the substrate 102, or, in embodiments, the adhesive 106 may be selected so as to not interfere with the degradability, compostability, and/or repulpability of the composite layer 104 and the substrate 102 so that the laminate structure 100 can be placed in an appropriate waste stream (e.g., landfill, compost, recycling, etc.).
  • the adhesive 106 could be a water-based glue or any other suitable adhesive.
  • the adhesive 106 may be a functional adhesive, e.g., an adhesive that provides properties in addition to bonding between surfaces, for example, adhesion promotion, dispersion of particles, hydrophobicity, hydrophilicity, tensile strength, tear resistance, anti-blocking, and heat resistance or stabilization, to name a few.
  • a functional adhesive e.g., an adhesive that provides properties in addition to bonding between surfaces, for example, adhesion promotion, dispersion of particles, hydrophobicity, hydrophilicity, tensile strength, tear resistance, anti-blocking, and heat resistance or stabilization, to name a few.
  • the adhesive 106 can have barrier properties to complement the composite layer 104 so that the adhesive 106 and the composite layer 104 cooperate to form a barrier layer 108 of the laminate structure 100.
  • the barrier layer 108 can be resistant to, e.g., can inhibit, minimize, and/or prevent, the passage of materials, e.g., food products, such as moisture, food grease, oils, oxygen, and/or other substances, for example.
  • the adhesive 106 is provided in a complementary relationship with composite layer 104 so as to minimize or eliminate a desired amount of porosity and/or permeability of the composite layer 104 to the passage of materials such as food products.
  • Adhesive 106 may be provided in a pattern or arrangement optimized for the reduction or elimination of the desired amount of porosity or permeability of the composite layer 104.
  • the barrier layer 108 formed by the adhesive 106 disposed on the composite layer 104 may have a porosity and/or permeability that is lower than a porosity and/or permeability of the composite layer 104 without the adhesive 106.
  • the laminate structure 100 can be formed by unrolling the composite layer 104 and the substrate 102 from respective rolls (e.g., in response to the action of one or more nip rollers), applying the adhesive 106 to an inner surface of the substrate 102 and/or the composite layer 104, and nipping the substrate 102, the adhesive 106, and the barrier paper layer 104 with one or more nip rollers (not shown).
  • the laminate structure 1 0 could be otherwise formed and/or could be otherwise arranged and/or configured without departing from the disclosure.
  • the laminate structure 100 could include additional layers and/or features.

  • the barrier layer 108 can help minimize, inhibit, and/or prevent food particles such as grease and/or other substances from penetrating to the coatings and/or colorants on the exterior of the laminate structure 100 so that the food grease and/or other substances can be at least partially prevented from discoloring and/or otherwise adversely affecting the exterior of the laminate structure 100.

Abstract

L'invention concerne une construction servant à contenir un produit alimentaire. La construction comprend au moins une paroi qui entoure au moins partiellement un intérieur de la construction. La ou les parois comprennent une structure stratifiée qui comprend un substrat et une couche composite formée de parchemin de qualité économique. La couche composite est stratifiée sur le substrat à l'aide d'un adhésif de telle façon que la couche composite et l'adhésif forment ensemble une couche de barrière. La couche composite présente une première porosité, et la couche de barrière présente une deuxième porosité inférieure à la première porosité.
